FEED-WATER HEATER.

QPECIPIQATION formihg part of Letters Patent No. 317,636, dated May 12,1885.

Application filed January 1885. (No model.)

To all whom it na-y concern:

Be it known that I, MICHAEL FUNK, a citizen of the United States,residing at La Grosse, in the county of La Crosse and State of lVisoonsin, haveinvented certain new and useful Improvements in Feed-Vater Heaters, of

which the following is a specification, reference being had therein tothe accompanying drawings.

This invention has relation to improvements in feed-water heaters; andit consists in the construction and novel arrangement of devices, aswill be hereinafter fully explained, and particularly pointed out in theappended claims. 1

The annexed drawings, to which reference is made, fully illustrate myinvention, in which Figure 1 represents a vertical sectional view, andFig. 2 is a detail sectional view of the same.

Referring by letter to the accompanying drawings, A designates the outershell or jacket, having the inlet-port a at the bottom thereof for thepassage of the exhaust-steam from an engine and the outlet-port b forthe escape of the same, and in one side of said l jacket 'is provided anopening, 0, surrounded on its outer sidewith a flange, (I, that receivesa removable cap, c, whereby said opening is closed. This hole permits ofthe hand being passed within the shell or jacket, in order that theinterior thereof may be readily cleaned.

13 represents the inner cylinder or waterreceptacle, which latter entersthe lower portion thereof through a connect-ingpipe, f, with the sameand the outer cylinder or jackct, having suitable packingboxes, asshown, and at the upper portion of said water-chamber is theoutlet-pipe, also having a similar connection with the outer shell. Saidshell or jacket is provided on its top plate with an opening, 9, whichis covered by a plate, 72, screwed securely thereto by the bolts 1', andwhich also serves as ahand-hole for theinterior of the heater or spacesurrounding the same. If desirable, two or more of the hand-holes in theside of the outer jacket may be provided.

The inner shell or waterheater consists of the cylinder portion, whichextends from the bottom plate of the outer casing nearly to the topplate thereof, having a space between the top plate of the same and thetopof said jacket. Said top and bottom plates of the inner cylinder areprovided with marginal flanges j, which are perforated to receiverivets, by which they are secured to said cylinder. The plates are alsoprovided with openings k, which have marginal flanges Z, by means ofwhich the flues m are riveted thereto.

Below the bottom plate, and between the same and the lower plate of theouter casing, is a space, 72, which communicates with the fines andprovides a passage for the Steam from the inlet-pipe. Said spaceissurrounded by the lower edge of the inner cylinder, forming aninclosure, and upon which said cylinder is supported, resting upon thelower plate of the outer cylinder or casing, as shown in the drawings.

The heater is provided with the usual drippipe and blow-pipe,of anyapproved construction.

It willbe seen by reference to the annexed drawings that the upper andlower ends of the flues are riveted to the flanges on the top and bottomof the inner cylinder, thus preventing leakage by contraction andexpansion at these points; also, the fines being large, (about sixinches in diameter,) permits a greater heating surface and a freecirculation of the exhauststeam from the engine and relieving the steamfrom back pressure, at the same time providing ample room between saidlines to remove all scales and impurities that accumulate from thefeed-water in the heater,which removal is accomplished through thehandhole, which cannot be done in heaters having small flucs or tubes,and by providing the large flues with thick material the same will notcorrode as quickly as smaller flues.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. The feed-water heater herein described, consisting of the outercasing, A, having the openings 0 in its vertical wall near the bottomthereof and arranged directly opposite the opening in the inner casing,and the inner casing, B, constructed as shown, said outer casingprovided with the flange d, encircling the opening 0, having theexterior screwthreads to engage interior threads in the cap 0, wherebyaccess may be had to the inner cylinder at its lower end, as and for thepurposes set forth.

2. In an upright feed-water heater, the combination,with the outereasing,constructed as shown, of the inner cylinder having at its lowerend the opening directly opposite the opening 0 in the outer casing, andprovided at its top and bottom with the plates of similareonstructiomhaving the outer flange to engage the inner wall of theinner cylinder, which is secured thereto, and each having the openingsto receive the upper and lower ends of the flues m, said openingssurrounded by the marginal flange Z, whereby said flues are secured tothe plates by bolts passing through the flange and flue, the wholearranged as shown and described.

7 3. In a feed-water heater of the class herein shown, thecombination,withthe outer e'ylinder or casing,constructed as described,of the inner cylinder, 13, provided with the flues m and the. opening,and the upper and lower plates having the flanged openings to receivethe fines and marginal flange, whereby said plates are secured to theinner cylinder by bolts, as shown, the lower plate arranged within thelower portion of said inner cylinder to form a passage between the sameand the bottom plate of the outer easing,the lower marginal edge of theinner cylinder serving as a support for the latter, and an inclosingwall for the space between the bottom of the inner cylinder and outercasing, the whole arranged as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL FUNK.
